       4. The battery module according to  claim 1 , wherein the recessed portion is a through hole and the mating portion is plug-connected to the through hole. 
     
     
       5. The battery module according to  claim 1 , wherein a plurality of mating portions are provided, and the plurality of mating portions are arranged at intervals. 
     
     
       6. The battery module according to  claim 1 , wherein the mating portion comprises a limiting hook. 
     
     
       7. The battery module according to  claim 6 , wherein the mating portion further comprises an extension portion connecting at least one of the first connecting plate and the conductive component to the limiting hook. 
     
     
       8. The battery module according to  claim 1 , wherein the conductive component is connected to the top cover of the failed battery unit through a connecting portion. 
     
     
       9. The battery module according to  claim 8 , wherein the conductive component comprises the connecting portion and a transition portion, wherein the transition portion is connected to the connecting portion. 
     
     
       10. The battery module according to  claim 1 , wherein the mating portion is configured to be a bump. 
     
     
       11. A battery group, comprising:
 a battery module, comprising:
 a plurality of battery units configured to be serially-connected, wherein the plurality of battery units comprises a failed battery unit and at least one non-failed battery unit adjacent to the failed battery unit after the battery module fails; 
 a first connecting plate configured to physically connect the failed battery unit to the at least one non-failed battery unit; and 
 a conductive component configured to be electrically connected to a top cover of the failed battery unit; 
 wherein one of the first connecting plate and the conductive component is provided with a mating portion, and the other of the first connecting plate and the conductive component is provided with a recessed portion configured to be connected to the corresponding mating portion in a mating manner, wherein the mating portion is configured to be connected to the recessed portion so that the battery module resumes working; and 
 
 a box body configured to accommodate the battery module. 
 
     
     
       12. The battery group according to  claim 11 , wherein the first connecting plate and the conductive component are clamp-connected or plug-connected through the mating portion. 
     
     
       13. The battery group according to  claim 11 , wherein the recessed portion is a through hole and the mating portion is plug-connected to the through hole. 
     
     
       14. An apparatus, comprising: a battery group, the battery group being configured to provide electrical energy, the battery group comprising:
